PRODUCT RECOMMENDATION
ROOF INSULATION SYSTEM
AERO-ROOF® is an insulation sheet laminated with aluminum foil and reinforced fiber. It is a lightweight insulation installed under the roof of the buildings to prevent heat from sunlight. Aero-roof is a thermosetting material which is made of special synthetic rubbers mixed with flame retardants, making it non-melt and non-flame spread when burnt.
- Heat, Water and Moisture Protection
- Non-flammable
- Non-fibrous and Odorless
- Heath safty and Environment friendly
- Easy Installation
Cell Structure
FIBERGLASS
(open-cell structure insulation) Fiberglass thermal insulation is made from compacted small glass fibers. Air occupies the spaces between the fibers which allow atmospheric air, moisture or water penetrates into the insulation. Fiberglass insulation is an open cell structure insulation, very high water absorption and water vapor permeability. When pouring water on the fiberglass, water can pass thru and fiberglass insulation becomes wet which means much less thermal insulation property (very high K.Value).Especially when insulation on low temperature application, moisture from atmosphere will be forced to penetrate into insulation mass and then insulation becomes wet throughout the insulation. K.Value will increase rapidly (K. Value of water=0.60w/mK), condensation will occurs continuously not only condensation area but also whole insulation system, resulting in short service life, fungi, bacteria and odor.
PU/PE FOAM
(semi-closed cell structure insulation) PU/PE foam are made of polyols and polyisocyanates mixed with HCFCs or
similar gases (ozone depletion gases) as a blowing agent. If the density is below 120 kg/m3, the wall of each cell is very thin and easily broken during process. This makes low density PU foam has water absorption value over 10% by weight according to ASTM D 1056, which is not classified as closed cell insulation. Lower density PU/PE foam has higher water absorption and water vapor permeability, while HCFCs gases slowly moving out from the insulation. When insulated on low temperature application, moisture from atmosphere will be forced to penetrate into insulation mass, and then K.Value will increase rather fast after use for a period of time. During fire accident, hydrogen cyanide gas (HCN) is generated, which is a toxic gas used in chemical weapons and is fatal within a few minutes.
AERO-ROOF (EPDM)
AERO-ROOF® is made from synthetic elastomer based material with a great number of tiny singular closed cell. A single cell is enclosed by walls, each cell contains dry gases (mainly nitrogen gas) emitted from blowing agent. Elastomeric closed cell is classified as closed cell when water absorption value is less than 10% by weight according to ASTM D 1056. Thousands of cell walls act as multi-layer water and moisture barrier, resulting in very low water absorption and water vapor permeability in comparison with other types of insulation materials. As described above, AERO-ROOF® has a low and stable thermal conductivity property of the insulation (low and sable K.Value), which is an ideal thermal insulation for low temperature applications with long service life.
